ANTIGREEPING DEVICE FOR RAILS.

Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed February 27,1915. Serial No. 10,918. V

To all whom it may concern:

Be it known that I, AUGUST J. DINKLAGE, a citizen of the United States, and resident ofEast Orange, county-of Essex, State of New Jersey, have invented certain new and useful Improvements in Anticreeping De vices for Rails, of which the following is a specification.

My invention relates to devices for preventing a creeping or longitudinal movement of railroad rails occasioned for instance by the constant recurrence of shocks at the joints and has for its object to provide a device of this character which is extremely simple in construction and easy of application and which operates with a maximum of efliciency under all conditions.

Other objects of my improvement will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings which illustrate various examples of my device and in which- Figure 1 is a side elevation of a railroad rail with one form of my improvementapplied thereto; Fig. 2 is a sectional View thereof on the line 2-2 of Fig. 1; Fig. 3 is a plan view of this form of-my device as it appears when in the position illustrated in Figs. 1 and 2; Fig. 4 is a side elevation showing the device unattached; Fig. 5 1s a cross-section of a railroad rail showing another form of my device being applied thereto; Fig. 6 is a similar view showing another form of my improvement; Fig. 7 is a plan view thereof with the railroad tie shown in section; Fig. 8 is a view similar to Fig. 5 showing another form of my anticreeping device and Fig. 9 is a side elevation of still another form thereof. I v

In the form shown in Figs. 1, 2, 3 and 4 the device comprises two clamping members 10 and 11 continued to form arms 12 and 12 which extend toward each other in a direction transverse to that of the memberslO and 11. The clamping members 10 and 11 and their continuing arms 12 and 12 are connected by means of an integral member,

13 which is inclined relatively to said arms 12' and 12 at a more or less acute angle thereto when viewed in plan-as in Fig. 3 and is preferably located nearer to the member 11 than to the member 10 or in other words is off-center, whereby the arm 12 is somewhat shorter than the arm 12 although this arrangement is not absolutely necessary. The clamping members 10 and 11 are provided on their inner surfaces with recesses 14 and 14' respectively, the recess 14 preferably extending across the inner face of the member 10 in an inclined direction to cause said device to assume an inclined position relatively to the railroadtie 15 when in operative combination with the rail, while the recess 14 for instance extends straight or substantially horizontally across the inner face of the member 11 as shown in Fig. 4. In other words the respective recesses 14 and 14 are preferably so arranged that lines drawn longitudinally through the same .will cross each other, the purpose of which will appear more fully from the description hereinafter. This form of my improvement may be constructed .of any suitable metal or other material and preferably so that in the normal unattached condition of the device the members 10 and 11 extend toward each other as shown by dotted lines in Fig. 2.

The device now being described may be attached to the rail with the aid of any suitable tool for instance by passing the member 11 over the oneedge of the base 16 of ther'ail 17 and then engaging the recess 14 with the opposite edge of said rail base 16 in the same manner as indicated in Fig. 5, The device shown in Fig. 2 will then occupy substantially the same position as does the device shown in Fig. 5 after which'the member 11 is gradually forced down and in this manner is forced outwardly by the rail base 16. This is continued until the recess 14 is opposite the opposed edge of the rail base 16 whereupon the member 11 is forced toward the member 10 when viewed as in Fig. 1 or in other words a twisting action about the arms 12 and 12 is exerted on the device to bring the recess 14 into line with the rail base whereby said recess 14 is caused to snap over said rail base under the influence of the resiliency of the device. The application of the device to the rail takes place in the neighborhood of a railroad tie so that in its final operative position the device will have its short arm 12 in engagement with the tie 15 and will be inclined relatively thereto as shown in Fig. 1, the degree of inclination ping action of thedevice, the arms 12 and 12 will be pressed closer together under such clearly apparent from the drawings.

being predetermined by the inclination of the recess 14 as will be clearly apparent.

Owing to the resiliency of the clamping members 10 and 11 the rail base 16 is frictionally engaged by the device and is firmly held in position thereon, this frictional engagement being increased by the tendency v canted in a substantially horizontalfplanerelatively to the rail base this being due to the fact that the resisting force of the tie 15 against the movement of the device in the direction of the arrow a is-exerted only on the short arm 12 or entirely at one side of the said device. This canting of the device in a horizontal plane is opposed by the railbase 16 so that-the vertical walls of the recesses 14 and 14 (are b this operation caused to firmly bite'or grip the outer vertical edges of, the rail base 16 as will Xe t the same time the resistance exerted by the tie 15 will tend to force said device into an 3 upright vertical position or rock it toward the vertical face of the tie 15, which change in position is opposed by the upper and lower surfaces of said railbase whereby the upper and lower surfaces of the recesses 14 and 14 are caused to firmly bite or grip the corresponding surfaces of said rail base 16.

' As the force exerted by the creeping tend-.

ency is opposed by thetie and by the gripresistance in the direction in which the strain takes place and by the action of the connecting member 13 will at the same time tend to move toward each other in the direction of their length so that the clamping members 10 and ll'will be drawn toward each other and the vertical Walls of the recesses 14 and 14 thus forced into still firmer engagement with the edges of the rail base. The rail base 16 is thus firmly and simultaneously-gripped at a plurality of points and in a variety of ways so that the creeping movement of the rail is immediately and effectively arrested.

Owing to the fact that the device is held in position on the rail base under a double tension, that is, the tension exerted by the arms 10 and 11 tending to spring together .and the tension exerted by said arms tendingto assume the normal position shown in Fig. 4, it is impossible for saiddevice to become unintentionally dislodged by the vibration caused by the traific over the rails or from any other cause. If the rail contracts or expands under temperature changes or fro-m other causes, this double tension will be sufficient to cause said device to be carried along and to accommodate itself to all changes in the physical characteristics of said rail without becoming disengaged therefrom. The form of my invention illustrated i -Fig. 5 comprises the clamping members 10 and 11. connected together by a straight continuing arm 12 and having recesses 14 and 14? which may be the same as in the form first described. The method of applying this device in operative position on the rail base 16 may be the same as hereinbefore set forth and is clearly indicated in Fig. 5. The form now being described when in 0-perativesposition preferablyoccupies an inclined position relative to the tie 15 and abuts against the same in approximately the same manner as does the device in Fig. 1, the only difference being that the tie is engaged by the arm 1-2 throughout its length. Under the creeping force exerted by the rail this form of my improvement is rocked toward the tie 15 whereby the upper and lower surfaces of the recesses 14 and 14 are caused to firmly bite or grip the corresponding surfaces of the rail base whereby the creepingtendency of the rail 17 is immediately checked. 'As the device is under a tension in the direction of its length when in operative position, the side edges of the rail base 16 will also be firmly engaged by the vertical walls of the recesses 14 and 14. Otherwise this form may be the same as the form first described.

As shown in Figs. 6 and 7 the device comprises the clamping members 10 and 11 continued to form arms 12 and .12 connected together by a member 13 as in the form shown in Figs, 1-4. The member 13 however, instead-of being inclined at an acute angle to the arms 12 and 12 as in- Fig. 3 extends at a more or less obtuse angle to said arms when viewed in plan as in Fig? 7. The clamping members 10 and 11 are provided with recesses '14 and 14 which in the example shown. extend substantially straight or horizontally across the inner face thereof so that this form of my device when in operative position does not incline away from the tie but has the arm 12 in surface engagement therewith. Under the influence of the creeping force this arrangement of my device is canted in a horizontal plane relatively to the rail base owing to the fact that the resistance of the tie ,15 is exerted entirely on the arm ,12 or at one side of the device. Otherwise the form now shown in the first four figures of the draw- It will of course be understood that surface engagement therewith as in Fig. 7.

Referring now to Fig. 8 it will be seen that the device shown therein is substantially the same as in Fig. 5 excepting that the clamping members 10 and 11 are continued or bent upon themselves to form depending, resilient members 10 and 11 having recesses 14 and 14 formed therein. The operation and construction ofthis form of my device may otherwise be the same as in Fig. 5, the difference being" that the present form owing to the shape of the clamping members is somewhat more resilient in a direction transverse to the rail base 16 than is the form shown in Fig. 5.

In Fig. 9 the device is approximately the same as in Fig. 1 excepting that the clamping members 10 and 11 are inclined toward each other so that the recesses 14 thereof are in line with each other when looking in the direction of the length of said device. The said recesses 14 may be parallel with each other when looking at an end of the device as in Fig. 9 or may be inclined oppositely so as to cross each other when viewed in this manner. In the latter case the twisting action referred to in connection with the form of my device first described will be present in this last form also when the latter is attached to the rail base. The said last form may otherwise be constructed and operate in the same manner as does the form shown in Figs. 1-4, or it may be arranged to correspond to the form shown in Figs. 6 and 7.

It will be seen that all the forms of my improvement comprise structures readily fashioned from straight, continuous bars of material, thus making it possible to produce same at a minimum cost and effort. The said device in all its formsis also readily applied to the rail base after the rail has been laid and secured and when in operative position effectively prevents or checks a creeping of the rail from any cause and at all times and at the same time operates with a maximum of efficiency under all conditions. i

Various changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of my invention.
